I'm from the Netherlands.
I'm planning a one-way trip from Miami to Seattle in August by rental car.
Does a four week trip offer enough time to enjoy and do sightseeing?
Only one driver.

My rough intinery I-40W; Georgia; Alabama; Oklahoma; New Mexico; Utah; Yellowstone; Seattle

Is this the most scenic route or should I consider the more nothern routes like I-80W and/or I-90W?

Are there any rental companies that don't charge a drop off fee when returning the car after a one-way trip?

What are the driving regulations about 16 year old kids without a licence? In some countries (NZ, Australia) these kids are allowed to drive when supervised by an adult.

thanks a lot,
Frits Heshusius
